  2. Black soldier fly Larvae (BSF larvae )
  3. Black soldier fly Pupae (BSF pupae)
  4. Adult black soldier fly (BSF)

The life cycle of BSF usually lasts from 38-45 days, going through 4 main stages of development, including Eggs, Larvae, Pupea, Adult Fly


The BSF eggs stage (day 0 to 4) is the first stage of the black soldier fly. At this stage, BSF breeders in Vietnam can sell black soldier fly eggs from their farms to propagate through other farms, thereby also creating a great source of income for fly farmers.

BSF Larvae

The BSF larvae stage (day 5 to 22) is the stage that creates the most value for black soldier fly breeders. At this stage, the fly farmers can sell the black soldier larvae for high-quality pet food, animal feed, larval oil extraction, fly larvae powder, chitosan extract… and many other applications in the industry and pharmaceutical industry.

BSF Pupa

The BSF Pupa stage (day 23 to 37) is the stage of cocooning black soldier fly pupation. After the black soldier fly pupae are harvested they are often mashed into pellets as a food source for livestock, poultry, fish, lizards, turtles, and even pets such as dogs, cats, and reptiles… can still be eaten. In addition, Black soldier fly pupae are also bought by many bird’s nest breeders as food for swallow bird called “Yen pupae”

Adult flies

In the BSF Adult stage (day 38 to 45), fly breeders keep them lay more eggs as possible to increase herds. In addition, when dead bodies of adult black soldier fly can be composted into organic fertilizer from high quality flies used for soil improvement. Fertilizer from the dead black soldier fly adults is being used by many organic vegetable farms in Vietnam

Are Black Soldier Flies Dangerous?

Black soldier flies are considered non-harmful. As adults, they do not have a mouth to eat, they can only absorb water and nectar in the wild to maintain energy for the body, focusing on the reproduction and maintenance of the species.

Because of the lack of a mouth, the flies will not bite, do not harm crops or pets … Because they cannot eat, they only survive for 8 to 10 days depending on the amount of the fat reserves collected in the larval stage.

  • Chicken food
  • As Food for aquarium fish.
  • Animal Feed.
  • Organic fertilizer, improving soil
  • Collect chitin from the black soldier fly cocoon
  • Squeezed and extracted into the BSF Larvae oil to replenish nutrients to fish
